What is mpak?

mpak is a package registry for distributing MCP servers that make AI agents smarter. Think npm for MCP servers.

mpak distributes MCP (Model Context Protocol) servers as MCP bundles. MCP is an open standard that lets AI agents connect to external tools and data sources through a unified interface.

Terminal window
# Search for MCP bundles
mpak bundle search postgres


# Run an MCP server instantly
mpak bundle run @nimblebraininc/echo

No manual dependency installation. No configuration. Just works.

The Problem

Section titled “The Problem”

AI agents are generalists. They become powerful when you give them specialized tools. But distributing MCP servers is a mess:

  • MCP servers require manual dependency management and complex setup
  • Discovery means searching GitHub and hoping you find something that works

Registries solved this problem for every other ecosystem: npm for JavaScript, PyPI for Python, crates.io for Rust. mpak does the same for MCP servers. Learn why a registry matters.
